Compressport R2 3.0 Compressport R2 3.0 calf sleeves are a follow-up to the very popular R2v2. For example, they have targeted compression, quick-drying material, or K-protect technology to protect the kneecap against shocks. The new fibular strips increase proprioception, which aids stability and reduces the risk of ankle sprains over unpaved trails. The compression sleeve tightly constricts the entire muscle group, which significantly reduces shocks that can cause micro-injuries in delicate muscle fibres, as well as fatigue and cramps. Furthermore, due to the constriction and narrowing of the bloodstream, blood circulation is accelerated and the muscle is more quickly oxygenated and effectively detoxified. Compressport R2 3.0
